HPUX11.11 - Using the script command and logname - error is "could not get login name"

Hi,

I am trying to use logname having started a script command and it comes back with:

# script me
Script started, file is me
# logname
logname: could not get login name

However come out of the script command and all is fine:

# script me
Script started, file is me
# logname
logname: could not get login name
#
Script done, file is me
# logname
mparsons

Is there a workaround for this?

Kind Regards,

Mark P.

HI

Try both:

a)
LOGNAME=`logname`
print $LOGNAME

b)
LOGNAME=$(logname)
print $LOGNAME

Re: HPUX11.11 - Using the script command and logname - error is "could not get login name"

Hi Mark:

The 'script' command starts a new shell process. When this process uses 'logname' to attempt to obtain the login terminal name, 'getlogin()' is called to find the name of the user logged in on a terminal associated with the calling process. This is done by searching the accounting database 'utmpx'. Since at that point, the process id of the 'script' command can't be matched, 'logname' fails.

You need to take the 'LOGNAME' variable from your environement, instead:

# echo ${LOGNAME}

Thanks for that - it does work - but doesn't help in the situation that I am working on.

The oracle account can only be accessed by relevant users and not as a direct login so I've got the following set in /etc/profile:

name=`logname`
if [ $name = oracle ]
then
echo $LOGNAME not allowed to login...only su
exit 0
fi
end

I'm also doing an audit trail on the relevant users by using the script command so this is part of the users profile:

Date=`date +'%Y%m%d%H%M%S'`
script /logs/script/$LOGNAME.$Date 2>/dev/null

So oracle cannot login direct. The user logs in direct - the session is copied into the script - then they do the "su - oracle" and then from the /etc/profile gets the message:

logname: could not get login name

Obviously the su login process and the script continues successfully - I just want to get rid of the "logname: could not get login name" message - anything will do!

Kind Regards,

Mark P.

su - oracle
is not the same as
su oracle

'-' means accept a new oracle environment
without means maintain the current environment.
